Subject Re: Giraph Stats - Sent messages=0
Date Mon, 09 Jan 2012 19:39:26 GMT
I could see how this is confusing.  "Sent messages" is a superstep based 
counter.  When the console prints the "giraph stats", they are for the 
last superstep, in that case, likely the number of sent messages is 0.  
If you have a long running application that sends messages, watch the 
job stats from the hadoop job webpage and you should see the "Sent 
messages" != 0 for intermediate supersteps.

Hope that helps,

and sentMessagesCounter.getValue() always return equal numbers. Thus the counters seam to
be up-to-date. Is there some flag I forget to set or where is a good spot to fix this?
